Inside, they are light and fluffy with pockets of melted chocolate and sweet banana in every bite.
This recipe is simple enough for a weekday morning and reliable enough for sharing. It is one of those dependable bakes that transforms a few ripe bananas into something everyone reaches for.

- 2 cups all purpose flour: This creates the structure of the muffins. Spoon and level the flour so you do not pack too much into the cup, which can make the texture heavy. You can substitute up to half with whole wheat flour for a slightly heartier crumb, though the muffins will be a bit denser.
- 1 cup granulated sugar: Sweetens the batter and helps form that golden, slightly crisp muffin top. For a deeper flavor, replace up to one third with light brown sugar for a subtle caramel note.
- 3 teaspoons baking powder: Provides most of the lift, helping the muffins rise tall and fluffy. Check that it is fresh for the best results.
- ½ teaspoon baking soda: Works with the acidity in the yogurt and banana to create a tender crumb and balanced rise.
- 1 teaspoon ground cinnamon: Adds warmth that complements both the banana and chocolate. You can add a small pinch of nutmeg for extra depth.
- ½ teaspoon salt: Balances the sweetness and sharpens the overall flavor. Fine sea salt works beautifully here.
- 1 cup mashed banana (about 2 to 3 ripe bananas): Brings natural sweetness and soft texture. The darker and spottier the bananas, the better the flavor. If you are slightly short, you can supplement with a few tablespoons of applesauce.
- ¾ cup plain Greek yogurt: Adds richness and keeps the muffins fluffy. Full fat yogurt gives the best texture, though low fat works well too. Sour cream makes an easy substitute.
- ½ cup oil: Keeps the muffins soft for days. Use a neutral oil such as canola or avocado. Melted butter can be used for a richer flavor.
- 2 eggs: Provide structure and stability. Room temperature eggs mix more evenly into the batter.
- 1 teaspoon vanilla extract: Rounds out the flavor and enhances the chocolate.
- 1 cup chocolate chunks: Creates pockets of melted chocolate throughout the muffins. Chocolate chips work fine, though chopped chocolate gives a more bakery style look. Use dark, semi sweet, or milk chocolate depending on your preference.

How To Make Chocolate Chunk Banana Muffins
Whisk the dry ingredients, whisk the wet ingredients, combine just until mixed, fold in chocolate, and bake until golden with a tall dome. Let me show you how:
- Prep the oven and pan: Preheat the oven to 375 degrees Fahrenheit or 190 degrees Celsius. Line a 12 cup muffin tin with paper liners.
- Mix the dry ingredients: In a large bowl, whisk together the flour, sugar, baking powder, baking soda, cinnamon, and salt. Whisking evenly distributes the leavening so the muffins rise uniformly.
- Mix the wet ingredients: In another bowl, whisk together the mashed banana, Greek yogurt, oil, eggs, and vanilla until smooth. The mixture should look creamy and fully combined.

- Combine wet and dry: Pour the wet mixture into the dry ingredients. Stir gently with a spatula until no streaks of flour remain. Stop mixing as soon as the batter comes together.
- Fold: Fold in the chocolate chunks.

- Divide batter: Divide the batter evenly among the muffin cups. A cookie scoop helps keep portions even.
- Bake muffins: Bake for about 20 minutes, until the tops spring back lightly when pressed or a toothpick inserted in the center comes out with a few soft crumbs.
- Cool: Let the muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.

Recipe FAQs
Yellow peels with brown spots are what you want. They are soft and mash up easily.
Do not overmix the muffins. Stir just until the ingredients are combined to help keep the muffins light and fluffy.
Use the toothpick muffin. If the toothpick comes out clean, the muffins are done baking.
Yes, thaw completely and drain any excess liquid before mashing.
Yes, bake at 350°F for 10 to 12 minutes.
You can reduce it by about 2 tablespoons without affecting texture too much, though the tops will be slightly less golden.
Bakery-Style Muffin Top Trick
For taller domes, start baking at 425°F or 220°C for 5 minutes. Without opening the oven, reduce the temperature to 350°F or 180°C and continue baking for 12 to 15 minutes. The initial high heat gives the muffins a quick burst of lift.

High Altitude Baking Adjustments
At elevations above 3,000 feet, reduce the baking powder to 2 1 half teaspoons and increase the flour by 1 to 2 tablespoons. You may need to add 1 to 2 tablespoons of extra milk if the batter feels thick. Check for doneness a few minutes early, as baked goods often cook faster at higher elevations.
If you bake frequently at higher elevations, be sure to check out my High Altitude Banana Bread for more detailed adjustments and testing notes specific to altitude baking.
